Speech Recognition: From the Laboratory to the Real World

Abstract
The art and science of speech recognition research have advanced to the point where it is now possible to communicate reliably with a machine via telephone to carry out simple tasks. However, the creation of robust algorithms is only part of the overall process of making speech recognition technology a commercial reality. In this paper, we present a brief overview of speech recognition technology and discuss the implementation of the algorithms with digital signal processing chips. In addition, we will show how theory and practice come together in real-world conditions by describing a telephone network trial of automatic credit card verification using speech recognition technology.
